Watch NASA’s DART spacecraft slam into an asteroid
NASA has slammed its DART spacecraft into an asteroid in the world’s first demonstration of planetary defense technology.
dart spacecraft
NASA’s DART spacecraft is about to smash into an asteroid
The DART spacecraft is now close enough to image the asteroid system it plans to slam into as part of NASA’s planetary defense efforts.
asteroid bennu
NASA was “completely wrong” about the asteroid Bennu
It wasn’t until landing on the asteroid Bennu that NASA learned its surface was more like a plastic ball pit than the relatively solid moon.
The cosmos can kill us in many ways. But the James Webb Space Telescope can help save us
Asteroid strikes, supernova explosions, and gamma-ray bursts are just a few of the ways the cosmos can kill us.
This is the damage a tiny speck of space debris can do at 15,000mph
A crater 5 inches deep was caused by something about the size and weight of an eraser on the end of a pencil.
What happens if the Solar System’s largest comet collides with Earth?
The asteroid that caused the last mass extinction 65 million years ago was only 5 kilometers across — tiny compared to this one.
potentially hazardous asteroids
We have a new way to hunt for potentially hazardous asteroids
To help protect Earth from potentially hazardous asteroids, astronomers developed an algorithm to look for them in existing datasets.
planetary defense
China is going to try to move an asteroid
As part of its new planetary defense strategy, the China National Space Administration is going to launch a mission to redirect an asteroid.
new Asteroid
New asteroid spotted just before impact with Earth
NASA successfully pinpointed almost exactly where and when a new asteroid would hit Earth’s atmosphere, before it made contact.
An asteroid could wipe out an entire city – here’s NASA’s plan to prevent catastrophe
Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet.
near-earth asteroid
This near-Earth asteroid may be a chunk knocked off of the moon
A near-Earth asteroid discovered in 2016 may have once been part of the moon — making it unlike any space rock we’ve ever discovered.

“Pulverize It”: The plan to slice and dice space rocks
To prevent asteroid impacts, UCSB physicists suggest we slice up the space rocks using arrays of “penetrator rods.”
asteroid heading to earth
Nuking an asteroid heading to Earth really could protect us
Blowing up an asteroid heading to Earth with a nuclear bomb could save the planet, according to new planetary defense simulations.

NASA updates the odds on Bennu asteroid hitting Earth
Using data from the OSIRIS-REx spacecraft, NASA has updated its predictions about the Bennu asteroid impacting Earth.
psyche asteroid
Psyche asteroid might not be a planetary core after all
The first high-res heat emissions map of the Psyche asteroid suggests the hunk of metal might not be the core of a developing planet.
asteroid impact simulation
Is NASA ready for an asteroid impact?
NASA is staging a week-long asteroid impact simulation during which participants will need to respond to a hypothetical impact scenario.
asteroid samples
Can Japan’s asteroid samples show us how life began?
JAXA’s Hayabusa2 has successfully returned asteroid samples to Earth. Its next mission? Gather information that could help prevent an asteroid impact.
space mining
Bacteria could make space mining 400% more efficient
Using a bioreactor packed with bacteria could make space mining more efficient by speeding up the extraction of elements from rock.
Bennu
Why NASA just landed a spacecraft on the asteroid Bennu
NASA has collected samples from the asteroid Bennu that could yield insights into everything from the origin of life to avoiding an asteroid impact on Earth.
